What Is Morus Alba Bark Extract?

Morus alba bark extract comes from the mulberry plant, which has been cultivated for centuries, particularly in sericulture (silk production). The bark contains a range of naturally occurring compounds, most notably flavonoids and alkaloids, which give the extract its biochemical profile.

In skincare formulations, this ingredient functions as a skin conditioner. It is used in a relatively small proportion of products, typically at concentrations below 1%.

How It Works

The flavonoids and alkaloids present in Morus alba bark extract function as antioxidants, meaning they can help neutralise free radicals that contribute to skin ageing and damage. Free radicals form naturally through sun exposure, pollution, and metabolic processes.

Beyond antioxidant activity, the extract appears to condition the skin by supporting its natural barrier function and maintaining hydration, though the precise mechanisms in topical skincare remain an area for further research.

Clinical Evidence & References

Research into Morus alba has identified a range of biological activities, including antioxidant and antimicrobial properties. Laboratory studies suggest the plant contains compounds with potential benefit to skin health, though clinical trials specifically evaluating the bark extract in cosmetic formulations are limited.

Most evidence comes from in vitro (laboratory) studies rather than controlled human trials, so claims about efficacy in skincare should be treated with appropriate caution. The ingredient appears well-tolerated, but robust clinical data on topical application in humans would strengthen confidence in its skincare benefits.

How to Use

This ingredient is typically found in leave-on formulations such as serums, essences, and moisturisers. There are no specific usage restrictions; it can generally be incorporated into your routine daily as part of a hydrating or antioxidant product. Combine with other protective measures such as sunscreen for optimal skin support.

Safety & Precautions

Morus alba bark extract is generally considered well-tolerated in skincare products. Sensitivity is rare, though patch testing is advisable if you have particularly reactive skin.
